Hired to hunt down a killer, he's taken the law into his own hands to save a life. No Matter the consequences.

Based on Lawrence Block’s best-selling crime thrillers, "A Walk among the Tombstones" stars Liam Neeson as Matt Scudder, an ex-NYPD cop who now works as an unlicensed private investigator operating just outside the law. When Scudder reluctantly agrees to help a heroin trafficker (Dan Stevens) hunt down the men who kidnapped and then brutally murdered his wife, the PI learns that this is not the first time these men have committed this sort of twisted crime…nor will it be the last. The deeper he gets into this criminal underworld, he quickly learns that the only things he can trust to keep himself alive are his own skills.
